Question

Suppose the simple pendulum in Exercise 54 were released from an angle of 60o.
In Exercise A simple pendulum has a length of 0.75 m and a bob with a mass of 0.15 kg. The bob is released from an angle of relative to a vertical reference line (Fig. 5.34).

(a) What would be the speed of the bob at the bottom of the swing?
(b) To what height would the bob swing on the other side?
(c) What angle of release would give half the speed of that for the release angle at the bottom of the swing?
